Technical specifications

Structural steel, alloyed chromium-silicon-manganese-nickel. This steel is difficult to weld, is sensitive to the formation of flokens, prone to temper brittleness. Hardness after annealing (GOST 4543−71): HB 10 -1 = 255 MPa. The hardness of a thick normalized sheet (GOST 11269−75) HB 10 -1 = 163 — 229 MPa. Supplier Avlob offers to buy a pipe, a circle, a rod of grade 30ХГСН2А, 30hgsna at an affordable price today. The best price from the supplier.
